About 20 years ago, the first application of PLC (programmable controller) for packaging machinery products opened the era of packaging machinery automation technology. The earliest semi-automatic/automatic packaging machines, such as semi-automatic balers and fully automatic balers, have emerged. Later, with the intervention of control and drive technology, servo technology and digital-to-analog conversion concept, the packaging machinery market has undergone several rounds of changes. At present, China has become the world's largest producer and exporter of goods. At the same time, the global focus is also on the fastest growing, largest and most promising Chinese packaging market.

Despite the broad prospects of the domestic packaging machinery market, such problems as single-machine automation, unsightly appearance, short life, stability and poor reliability have also caused domestic packaging machinery products to suffer from criticism. Professor Li Zhenliang from the School of Mechanical Engineering of Tianjin University of Science and Technology deeply felt: "China's packaging industry has weak self-development capabilities and lacks a base for scientific research and production. At the same time, there are few leading enterprises with large domestic production scale. In fact, with Germany, Italy and other countries. Compared with the packaging machinery products, the gap is the room for domestic machinery manufacturers to rise, especially in the automatic metal belt balers such as metal belt machinery."
Flexible production – making product packaging more flexible
At present, in order to adapt to the fierce competition in the market, the major enterprises are getting shorter and shorter. For example, the production of cosmetics can generally be changed in three years, even in a quarter, and the demand is relatively large (such as the wooden packaging used for packaging equipment), so the flexibility and flexibility of the packaging machinery is very high. Requirements: The life of the packaging machine is much longer than the life cycle of the product. The concept of flexibility can be considered mainly from three aspects: the flexibility of quantity, the flexibility of construction and the flexibility of supply. Specifically, in order to make the packaging machine have good flexibility and flexibility, and to improve the degree of automation, it is necessary to adopt microcomputer technology, functional module technology and the like. For example, on a food packaging machine, different units can be combined on the basis of one machine, and multiple types of products can be packaged at the same time by using multiple feed ports and a plurality of different folded packaging forms. Multiple robots operate under the supervision of a host computer and package different types of foods in different ways according to the instructions. If there is a product change request, just change the calling program in the host.
The field of safety inspection is gradually expanding
Safety is the number one keyword in any industry, especially in the packaging industry. In the food industry, safety detection technology has developed rapidly in recent years. Specifically, it is to improve the precision of the ingredients in the mechanical products. At the same time, it is necessary to be able to record information such as the storage operator, the type of ingredients, the production time, and the equipment number. We can achieve our goals through features such as weighing, temperature and humidity sensors.
Motion control technology
The development of motion control technology in China is very rapid, but the development momentum in the packaging machinery industry is lacking momentum. The role of motion control products and technologies in packaging machinery is mainly to achieve precise position control and strict speed synchronization requirements, mainly for loading, unloading, conveying, marking, palletizing, depalletizing and other processes. Professor Li believes that motion control technology is one of the key factors distinguishing high, medium and low-end packaging machinery, and it is also the technical support for the upgrading of packaging machinery in China. Since the entire machine in the packaging industry is continuous, there are extremely high requirements for speed, torque, accuracy and dynamic performance, which also fits the characteristics of the servo products.
Manufacturing execution system applications need to break through the bottleneck
In recent years, integration technology has developed rapidly in the packaging industry. There are many types of packaging machinery and equipment, which makes the transmission interface between different manufacturers' product interfaces, equipment and industrial computer, and information and equipment encounter great problems. In this case, the packaging company turned to the Manufacturing Execution System (MES) for a solution. However, it is understood that the application of MES in the packaging industry is not as good as people expected.
